Are you tired of restrictive diets that leave you feeling unsatisfied and still not achieving your fitness goals? Fear not, my friend, because IIFYM (If It Fits Your Macros) is here to save the day!
IIFYM is a flexible dieting approach that allows you to eat whatever you want, as long as it fits within your daily macronutrient goals. So, if you’re craving that slice of pizza or a scoop of ice cream, go ahead and indulge! The key is to make sure it fits within your macro goals, which we’ll calculate for you. Don’t worry, you won’t have to do any math because we have the formula for you:
Total Daily Energy Expenditure (TDEE) = BMR x Activity Level Multiplier
TDEE is the total number of calories your body burns in a day, taking into account your basal metabolic rate (BMR) and activity level multiplier. BMR is the number of calories your body burns at rest, and the activity level multiplier represents the number of calories you burn based on your daily physical activity.
Now that you know the formula, let’s dive into the different categories, types, ranges, and levels of IIFYM calculations and how to interpret your results.

Categories of IIFYM Calculations
Calculating your IIFYM macros starts with identifying your activity level. The categories of IIFYM calculations are as follows:
| Category | Description |
|---|---|
| Sedentary | Little to no exercise |
| Lightly Active | Light exercise or sports 1-3 days a week |
| Moderately Active | Moderate exercise or sports 3-5 days a week |
| Very Active | Hard exercise or sports 6-7 days a week |
| Extra Active | Very hard exercise or sports, physical job or training twice a day |
Based on your activity level, you will use a different multiplier in the TDEE formula to calculate your daily caloric needs.
IIFYM Calculation Examples
Let’s put the IIFYM formula and categories into practice with some examples! Meet John and Jane, two individuals with different activity levels and macronutrient needs.
| Name | Age | Gender | Weight (lbs) | Height (in) | BMR | Activity Level Multiplier | TDEE |
|---|---|---|---|---|---|---|---|
| John | 30 | Male | 180 | 72 | 1856 | 1.55 | 2878 |
| Jane | 25 | Female | 140 | 65 | 1363 | 1.725 | 2352 |
John is moderately active, meaning he exercises 3-5 days a week. Jane is very active, meaning she exercises 6-7 days a week. To calculate their TDEE, we used the appropriate activity level multiplier for each individual in the formula.
Ways to Calculate IIFYM
Now that you know your daily caloric needs, the next step is to determine your macronutrient goals. There are several ways to calculate IIFYM macros, each with its own advantages and disadvantages.
| Method | Advantages | Disadvantages | Accuracy Level |
|---|---|---|---|
| Online IIFYM Calculator | Quick and easy | Limited customization | Moderate |
| Manual Calculation | Precise | Time-consuming | High |
| TDEE Tracking Apps | Convenient | Based on estimations | Low |
Online IIFYM calculators are a popular choice because they’re quick and easy, but they may not be as precise as manual calculations. Manual calculations take more time but are generally more accurate. TDEE tracking apps are convenient, but they’re based on estimations and may not be as accurate as other methods.
Evolution of IIFYM Calculation
The IIFYM concept has evolved over the years. Here’s a look at the timeline of its evolution:
| Year | Evolution |
|---|---|
| 2004 | First IIFYM Calculator created |
| 2010 | Introduction of mobile apps for tracking |
| 2015 | IIFYM becomes more mainstream |
| 2020 | IIFYM evolves to include nutrient timing |
As you can see, the IIFYM concept has come a long way since its inception in 2004. Today, it’s a popular dieting approach that has helped many people achieve their fitness goals.
Limitations of IIFYM Calculation Accuracy
While IIFYM is a flexible and effective dieting approach, there are some limitations to its accuracy. Here are some of the most common limitations:
- Inaccurate Food Labeling: Many food labels don’t list accurate macronutrient information. This can make it challenging to track your macro intake accurately.
- Individual Differences: Everyone’s body is different, and IIFYM calculations don’t take into account individual factors like metabolism and hormonal imbalances.
- Lack of Micronutrient Consideration: IIFYM only focuses on macronutrients, so it may not provide sufficient micronutrients. It’s important to make sure you’re getting enough vitamins and minerals in your diet as well.
Alternative Methods for Measuring IIFYM Calculation
If you’re looking for alternative methods to measure your IIFYM macros, there are a few options to consider. Here are some of the most popular alternative methods, along with their pros and cons:
| Method | Pros | Cons |
|---|---|---|
| Hand Portion Control | No need for tracking | Less precise |
| Body Composition Testing | Provides accurate macronutrient needs | Expensive |
| Calorie Cycling | Can boost metabolism | Requires more planning and effort |
Hand portion control is a simple and intuitive way to manage your macro intake without tracking your food. Body composition testing is a more accurate way to determine your macro needs, but it can be expensive. Calorie cycling is a strategy that involves alternating between high-calorie and low-calorie days to boost your metabolism, but it requires more planning and effort than other methods.
FAQs on IIFYM Calculator
- What are macronutrients? Macronutrients are nutrients that provide energy and are essential for body function, including carbohydrates, proteins, and fats.
- How do I track my macronutrients? You can use a food tracking app or manually track your intake using the nutrition label on food.
- Can I eat junk food on IIFYM? Yes, as long as it fits within your daily macronutrient goals.
- Do I have to eat at specific times on IIFYM? No, IIFYM focuses on daily macronutrient goals rather than specific meal timings.
- Can I still lose weight on IIFYM? Yes, as long as you are in a calorie deficit.
- What is a good starting point for macronutrient ratios? A common starting point is 40% carbohydrates, 30% protein, and 30% fat.
- Can I adjust my macronutrient ratios? Yes, as long as the new ratios still fit within your daily macronutrient goals.
- Is IIFYM suitable for everyone? No, it may not be suitable for those with certain medical conditions or specific dietary needs.
- How long should I follow IIFYM? It can be followed long-term as a lifestyle, but it’s important to periodically reassess your goals and adjust your macronutrient goals accordingly.
- Can IIFYM help with muscle gain? Yes, as long as you are in a calorie surplus and getting enough protein.
